CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 435,0'72, dated August 26, 1890.

Application filed February l2, 1890. Serial No. 340,234. (No model.)

To all whom t may concern:

Be it known that I, DAvID JOSEPH MARX, of Chicago, Cook` county, Illinois, have invented a new and Improved Automatic Coupling, of which the following` is a full, clear, and exact description.

My invention relates to that class of carcouplers having a pivotal swinging pin for use with an ordinary link; and an object of my invention is to provide means for lifting and lowering the said pin.

My invention further relates to the improvev ment of a car-coupler which shall provide an automat-ic means of both coupling and uncoupling ordinary link couplers without the use of springs, ropes, cables, pulleys, and chains, which are easy to get out of order.

Another object of my invention is to provide a crank-arm coupler and uncoupler free to give with the draw-bar springs, there being no part attached to the body or woodwork of the car; to provide a coupler requiring less exertion to operate than in levercouplings now in use, and to provide a cheap, neat, and secure device Well adapted for use on all classes of cars. by the mechanism illustrated in the annexed drawings.

Like figures and letters denote like parts in the separate figures.

Figure l shows a perspective side view of opposing draw-heads in position for coupling, having my improved device attached. Fig, 2 shows a longitudinal side view Vof the same. Fig. 3 shows a broken front, top, and inside view showing the link engaged or coupled. Fig. 4 shows a sectional view showing modifications explained hereinafter.

The draw-head A is provided with the iiaring mouth common to ordinary link couplers. Situated on the floor of the inside of the draw-head CZ is the shoulder or flange D, the top surface of which is arched or hollowed out at D to accommodate the crankbar I, bent in the shape of a double crank D O. This, the link-lifting device, is suspended from its a-Xes I-I, so as to embed itself in the cavity D', so as to escape and pass under the link G as it passes inward. The crank-bar I is provided with handles J within easy reach from the sides of the car.

Protrudin g from the crank-bari are two iin- I attain these objects gers or cams K, one on each side of the outside of the draw-head. Vhen handles J are turned upward, they bring these cams in position to bear against the sides P of a lifting device or frame F. This frame is swiveled to the flange of draw-head L by means of the bolts or pivots M, and the sides Pare mortisejoined to the front Q, and of which the outer ends are threaded for the reception of nuts O, which may be riveted and made fast. Suspended from the center of the front of the frame F is the p in B, which is free to swing on its pivotal axis in the perforation in the head of the pin. Provided in the top of the draw-head is the peculiar-shaped slot C. Passing through this slot-is the pin B, so as to bear against the forward edge of the said slot at the top, and the flange or shoulder D, provided at the bottom, and both bearings being cut away at an angle facilitates the hanging of the pin at an angle when engaging the link G and when at rest, which adds strength. Then the cams K are brought to bear against the sides P of the lifting-frame F, and force it and the pin suspended thereto upward to a sufficient height to draw the pin from out the link, they are checked from further progress by the brakes N.

From the foregoing it will be seen that the operation of my improved car-coupler is as follows: The entering link G strikes against the front surface of the pin B, forcing it backward and upward until the link passes inward, when gravitation sends the pin forward and downward through the link and rest- Aing' the said pin against its angular bearings,

before described, thus securely coupling said link automatically. When the cams l' are brought to bear against the sides P of the frame F, by turning handles J upward it draws the pin B upward through slot O and from out link G, releasing said link automatically. Vhen the handles J are reversed downward, they allow the pin to drop into its normal position to couple. Should it be desired to couple two cars thevdraw-heads of which are of unequal height, the operator turns the crank-handlej of lower draw-head forward, (the double crank D C being underneat-h the link G in its cavity D-,) raising the said link to the flaring mouth of the opposite draw-head.

loo

In Fig. 4, showing a modified view, the linklifting device consisting of the double crank D C, instead of being joined to the crankarms as one piece, is separated and swiveled y to the sides of the draw-head by means of the bolts m. The crank arms or bar I passes through the draw-bar in a straight line, instead of being bent, and carrying the outside cams lo and the inside hooks or cams K O, which bear against the double crank D C.

Having thus :fully described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, in a car-coupler, of the draw-head A, provided with the peculiar angular-shaped slot C, the angled flange D, the arch shaped cavity D', the crank bar or arms I, bent into the double crank D C, resting on the axes I-I, having the handles J, the cams K, and the brakes N, substantially as and for the purpose described.

2. The combination, in a car-coupler, of the draw-head A, provided with the rear flangel L, the U-shaped pin or lug lifting frame F, swiveled to the flange L by means of the bolts M, the pin or lug B, suspended on its pivotal swinging axis by the perforation in its head E from the center of the frame F, and the link G, substantially as and for the purpose described.

3. In a car-coupler, the combination of a draw-head having a pin-opening through the top and a fiange or stop on the bottom coinciding with the front of the pin-opening, a pinl and a swinging frame or bar to Which said pin is attached, a crank for operating the link, and a cam for operating the pin frame or bar, as set forth.

4. In a car-coupler, the combination of a draw-head having an elongated and undercut or beveled pin-opening through the top, a' ange or stop on the bottom, and a depression or recess in front of said flange or stop, a swinging and lifting pin and a frame or bar to which it is attached, said frame or bar being pivoted to the top of the draw-head, a crank working Within the draw-head having its horizontal limb lying in the depression or recess, and a cam on shaft of said crank for operating the pin frame or bar, as set forth.

5. The combination of a draw-head having a top flange or projection on the rear thereof and provided with a pin-,opening through the top and a projection or stop on the bottom, asdescribed, a frame consisting of side bars pivoted to the top flange and a rod connecting the front of said bars, a coupling-pin swiveled on said rod, a crank for operating the link, and a cam connected to the shaft of the crank for operating the frame, as set forth.

6. The combination of adraW-head having a pin-opening through the top and a stop or iiange in the bottom, a swinging and lifting pin, and a cam vfor raising said pin, as set forth.

f7. The combination, With a draw-head having a pin-hole through the top, a stop i-n the bottom, and a projection or brake on the side, of a pin and a cam for raising said pin, the movement of the cam being limited` by the brake, as set forth.
